Appeal 2007-2413
Application 10/041,117
1. A system for bypassing an aneurysm, comprising:
a first prosthesis, defining a single flow channel conduit, having a
proximal end and a distal end, including a self-expanding lattice and graft
material covering at least a portion of the self-expanding lattice, the graft
material having longitudinally oriented pleats, the first prosthesis being
configured to expand an artery into which it is positioned and anchor and
seal the system within the artery;
a compressible gasket positioned within the distal end of the first
prosthesis, the compressible gasket comprising at least two apertures therein;
and
at least two bypass prostheses in fluid communication with the first
prosthesis via the distal end of the first prosthesis, the at least two bypass
prostheses having proximal and distal ends, wherein the distal ends of the at
least two bypass prostheses are configured to anchor the at least two bypass
prostheses downstream of the aneurysm and the proximal ends of the at least
two bypass prostheses are configured to pass through the at least two
apertures in the compressible gasket positioned in the distal end of the first
prosthesis such that fluid flow paths are established, the compressible gasket
being configured to engage and seal the at least two bypass prostheses to the
first prosthesis.
The Examiner relies on the following art:
Rhodes US 5,843,160 Dec. 1, 1998.
Lunn US 5,476,506 Dec. 19, 1995.
Dereume US 6,554,858 B2 Apr. 29, 2003.
Claims 1, 6, 21, and 24 stand rejected under 35 U.S.C. §102(b) as
being anticipated by Rhodes. Claim 20 stands rejected under 35 U.S.C.
§ 103(a) as being rendered obvious by Rhodes. Finally, claims 1, 6, 20, 21,
and 24 stand rejected under 35 U.S.C. § 103(a) as being rendered obvious by
the combination of Dereume and Lunn.
We affirm.
